Vocab: tendon-a band of tough connective tissue that connects a bone to muscle. ligament-fibrous tissue that connects bones to bone. origin-the point where the main muscle connects to the bone (little movement) insertion-the point where a muscle connects to a bone in a join or area where a lot of movement is common. belly (of muscle)- the main part of the muscle, where the most muscle mass is. abduction-the movement in which limbs move away from the body. adduction-the movement that pulls limbs toward the body. extension-the movement of moving a limb away from the body while extending the limb the muscles also extend. flexion-a position that is possible by a joint angle decreasing.
1. Move and manipulate the various appendages. Describe their movement. What do you find interesting about each of these? When appendages are moved in a forward motion there are muscles that move forward and some muscles that also retract in an opposite motion.
2. Where do the muscles attach to the bone? The muscles connect to the bones at joints with tendons.
3. How does where they attach determine the movement of the appendage? Where muscles connect controls which way an appendage turns and rotates. If muscles are how they normally are on a human the arms will move forward when the muscles contract, but if the muscles are placed on the opposite side of the arm the arm would move backwards when the muscles are contracted.
4. What are some of the differences between the muscle and the tissue where the muscle attaches to the bone? Muscles are a collection of tissues and the tissue where the muscle attaches to the bone is made of mostly cartilage.
5. Are there differences in the ways different muscles attach within the same organism? Yes there are many different ways that a muscle attaches in an organism. There is the origin and insertion point. The origin is the area that is attached to a bone that is not moved or is moved very little. The insertion point is the muscles that are attached to areas that move a lot. The insertion point always moved toward the origin.
6. How are the attachments of the muscles similar and different among all the organisms including human muscles? They are alike because all of the muscles in any organism connect to bones by using tendons. They are different because every organism has different muscles and every muscle moved in a different way.
7. What composes the tissue that connects the muscle to bone? The tissue that connects the muscle to the bone is made of cartilage.
